Abstract

The invention relates to a three-dimensional grid simplifying method and device, electronic equipment and a storage medium. The method comprises the steps: acquiring a three-dimensional grid model of a target object, and converting the three-dimensional grid model into a two-dimensional grid image, wherein the three-dimensional grid model comprises a plurality of three-dimensional triangles; obtaining a two-dimensional mask image, wherein the size of the two-dimensional mask image is the same as that of the two-dimensional grid image, the two-dimensional mask image comprises a target mask area; determining a two-dimensional target area corresponding to the target mask area in the two-dimensional grid image, wherein the two-dimensional target area comprises a plurality of two-dimensional target triangles; and determining a three-dimensional target triangle corresponding to the two-dimensional target triangle in the three-dimensional grid model, and taking a three-dimensional grid formed by the three-dimensional target triangle as a simplified three-dimensional simplified grid. According to the scheme, the three-dimensional grid of the human face can be effectively simplified, and the refined beauty makeup special effect on the specific area can be achieved in various scenes.

Description

technical field [0001] The present disclosure relates to the field of image processing, and in particular to a simplified method, device, electronic equipment and storage medium for a three-dimensional grid. Background technique [0002] At this stage, smart terminals such as mobile phones and tablet computers often provide users with special effects for specific objects, such as three-dimensional beauty filters and virtual characters, during the process of shooting or playing videos. Taking 3D cosmetic special effects as an example, it usually needs to establish a 3D grid model for the face, and then render based on the grid to obtain 3D cosmetic special effects and display them. However, because the 3D mesh model often has a large number (such as 10,000) of 3D mesh vertices in order to achieve a richer detail display effect, the refined rendering puts forward higher requirements on the performance of the device, and often results in The device gets hot, the program freeze...
